Purpose of this Guide

This guide contains technical and product-related information on the SST-PB3-VME-1

and SST-PB3-VME-2 network interface cards.

The SST-PB3-VME-1 consists of a single Profibus network interface (or channel), and the

SST-PB3-VME-2 comprises two independent interfaces, controlled by independent CPUs.

Each CPU executes downloadable application firmware modules, which enable application-level

product behavior. For more details, refer to relevant firmware documentation.

Note

An application running on one channel does not affect the performance

of other channels, as it does not share memory or processor resources

with them.

Note

In this manual, the SST-PB3-VME-1 and SST-PB3-VME-2 will be

referred to as the card, except where product differences apply.

1.1 Warnings and Cautions

The card is an electrical component and must be treated with the following precautions:

Warning

Only qualified electrical personnel familiar with the construction/

operation of this equipment and the hazards involved should install,

adjust, operate, and/or service this equipment. Read and understand this

guide in its entirety before proceeding. Failure to observe this precaution

could result in severe bodily injury or, in extreme cases, loss of life.

Warning

You must provide an external, hand-wired emergency stop circuit

outside the programmable controller circuitry. This circuit must disable

the system in case of improper operation. Uncontrolled machine motion

may result if this procedure is not followed. Failure to observe this

precaution could result in bodily injury.

Caution

The card contains static-sensitive components. Careless handling may

severely damage the card. Do not touch any of the connectors or pins on

the card. When not in use, the card should be stored in an anti-static bag.

Failure to observe this precaution could result in damage to or

destruction of the equipment.

1.2 Card Features

The card is a VME interface for communication with Profibus networks. Each channel can:

•Act as a DP master

•Act as a DP slave

•Send and receive FDL (layer 2) messages

•Support Master Class 1 and Master Class 2 messaging

•Support simultaneous operation in all of the above modes

•Support the standard Profibus baud rates of 9.6K, 19.2K, 93.75K, 187.5K, 500K, 1.5M,

3M, 6M and 12M baud

•Support 16-bit transfers (VME D16) with both VME A24 (standard) and A16 (short I/O)

address transfers

Note

For A16 short I/O cycles, registers are located on the odd byte addresses

(0x01, 0x03, and so on) and are 8 bits wide.

Note

Applications running on one channel do not affect the performance of

other channels and do not share memory or processor resources with

other channels.

1.3 Byte Ordering

The card uses Intel-style (little endian) byte ordering for multi-byte entities LSB-low address and

MSB-high address. If your host system uses Motorola (big endian) byte ordering (MSB-low

address and LSB-high address), you must compensate for byte ordering in software.

The following language macro will compensate for byte ordering in a 16-bit data entity:

#define SWAP_WORD (WordData) ((WordData<<8) | (WordData>>8))

1.4.1.1 SYSFail LED

The SysFail LED indicates the system’s status.

Table 2: SysFail LED Behavior

LED State Meaning

Green This is the default power-up state. If the SysFail bit in

the VME register is set to a logic “1”, the LED will turn

red.

Red An error has occurred in the system. The system fail

signal is asserted on the backplane.

1.4.1.2 Watchdog LED

The Watchdog LED indicates that a watchdog timeout has occurred on the channel.

Table 3: Watchdog LED Behavior

LED State Meaning

Off This is the default behavior at power up. Indicates that

status is good and no timeout has occurred.

Red A watchdog timeout has occurred
